You may not be an expert tailor, but you don't need any special skills to know if a suit fits perfectly. All you need is your hands and a mirror.

You can measure each part of the jacket and pants just by eyeballing where they fall, and by using a few tricks with your hands. Esquire lines out seven things you can check right off the bat:

Shoulder pads end with your shoulders.

Your flat hand should slip easily into your suit under the lapels when the top (or middle) button is fastened. If you put a fist in, the suit should pull at the button.

The top button of a two-button suit - or the middle button of a three-button suit - should not fall below your navel.

With your arms at your sides, your knuckles should be even with the bottom of your jacket.

Jacket sleeves should fall where the base of your thumb meets your wrist.

Between a quarter and a half inch of shirt cuff should be visible.

One inch of break [in the leg].

If any of these don't fit the way they're supposed to, then you'll need to head to a tailor, but you can at least see what needs tailoring just by following these simple tips. Hit the link to learn more.
